Answer 1

Answer:

$\frac{17}{15}$

OR ALSO CAN BE WRITTEN AS

$\frac{34}{30}$

Step-by-step explanation:

Finding the LCM of 10 and 15, we get:

LCM = 30

Equating the denominators to 30 we get,

$\frac{ - 21}{30} + \frac{ - 26}{30} + \frac{81}{30} \\ = - \frac{21}{30} - \frac{26}{30} + \frac{81}{30} \\ = \frac{ - 47}{30} + \frac{81}{30} \\ = \frac{34}{30}$

You can simplify 34/30 to 17/15.
